Impedance analyzers


An advanced, comprehensive solution for the electrical characterization of materials

An impedance analyzer with the features and specifications necessary for working on a the broad range of applications in the field of materials research.

An advanced, comprehensive solution for the electrical characterization of materials

A modern materials science lab faces challenging measurements every day, and impedance spectroscopy is a primary tool in materials research enabling the characterization of the electrical properties of materials.

With a wide frequency range (10 µHz – 35 MHz) and high-levels of accuracy (0.1% amplitude, 0.05% phase) the BioLogic MTZ-35 impedance analyzer has been designed to tackle even the most difficult measurements required by materials science.

The MTZ-35 is the key instrument in integrated solutions for the electrical characterization of materials. These solutions, dedicated to wide-ranging applications and temperature ranges, consist of the MTZ-35 impedance analyzer, a temperature control unit, a sample holder and MT-lab software. The MT-Lab interface allows the control of many temperature control systems (HTF-1100 furnace, ITS, etc.) over a wide temperature range (from -40 to 1100°C).  It also allows impedance measurement and the modeling of EIS data with equivalent circuits. Many sample holders (CESH, HTSH-1100, HTCC) covering various materials types (polymers, ceramics, composites, ionic liquids, gels, etc) are compatible with the MTZ-35.
